Super Down ULTRA Jacket
lifetime warranty on all our gear
INCREDIBLY LIGHTWEIGHT, PACKABLE, AND WARM
The Super Down ULTRA Jacket weighs a mere 6.4 oz. It's built for the hunter looking for unbelievable warmth-to-weight ratio. It's designed with a mid-layer fit, making it an ideal insulating layer—or as a standalone jacket when brush-busting durability isn’t required. It's insulated with 2 oz of 850+FP TORAY Quixdown (50% less down than Super Down PRO), making it KUIU’s lightest down jacket.
Our Super Down products outperform the competition. We start with the best Polish goose down, which is cleaned, refined and processed by Kawada Feather in Meiwa, Japan. Their proprietary techniques perfect the down to a remarkable 850+ fill power and 95:5 down to feather ratio. Once cleaned, we treat the down with TORAY’s DWR, so each individual cluster is impervious to water; keeping its insulating loft even when wet.
The outer ultralight 12D nylon Stunner Stretch fabric is wind-proof and comfortable. It's heat-treated to keep the down from migrating through the fabric, eliminating the need for noisy down-proof coatings. The fabric is also treated with TORAY K-DWR to repel light rain and snow.
The positioning of the front pockets is above the belt line, offering accessibility while wearing a pack. The jacket compresses and self-stows inside the left zippered pocket for compact storage. It’s so lightweight, you won’t regret having it in your pack.

Quixdown® by Toray
Down has the highest warmth-to-weight ratio of any insulation material. The only drawback is that once wet, down stops being effective. Not anymore. Through nanotechnology, Toray Industries has created a water repellent finish for down feathers that makes each down cluster essentially waterproof. Quixdown® stays dry to keep you warmer with less weight and bulk.

Lightweight, Stretchable Comfort
Toray develops a new fabric technology and KUIU brings it to Mountain Hunters first! Ultralight, down-proof Stunner Stretch fabrics stretch as you move and put a layer of luxurious comfort between you and the warm softness of KUIU’s premium Polish down. And, of course, Stunner Stretch minimizes bulk and weight.

Toray’s Kudos® XR DWR
Kudos® XR DWR (Durable Water-Repellent)
Kudos XR DWR performs better and lasts significantly longer than conventional DWR. DWR is critical for waterproof breathable face fabric. If DWR fails the face fabric “wets out” causing condensation build up on the inside of the garment.
